Description
Verfahren zur Herstellung substituierter Imidazolderivate Process for the preparation of substituted imidazole derivatives
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von substituierten Imidazolderivaten der Formel (II) The present invention relates to a process for the preparation of substituted imidazole derivatives of the formula (II)
ausgehend von Verbindungen der Formel
starting from compounds of the formula
über Zwischenstufen der Formel (IV a) oder (IVb) via intermediates of the formula (IV a) or (IVb)
in denen die in den Formeln (I), (II), (IVa) und (IVb) angegebenen Strukturelemente die nachstehend angegebenen Bedeutungen haben. in which the structural elements given in the formulas (I), (II), (IVa) and (IVb) have the meanings given below.
Ferner betrifft die Erfindung die Zwischenstufen der Formeln (IVa) und (IVb). The invention further relates to the intermediate stages of the formulas (IVa) and (IVb).
Substituierte Imidazolderivate der Formel (II) haben große technische Bedeutung für die pharmazeutische und die agrochemische Industrie und sind beispielsweise wichtige Zwischenprodukte unter anderem bei der Herstellung von Verbindungen, die beispielsweise als Pestizide wirksam sind. Entsprechende Imidazole zur Verwendung als Pestizide und Verfahren zu deren Herstellung sind beispielsweise beschrieben in WO 2013/180193, WO 2016/039444, WO 2018/130437 und WO 2018/130443.
Die im Stand der Technik beschriebenen Herstellungsverfahren umfassen allerdings Methoden, die aus industrieller Sicht wirtschaftlich nicht zu realisieren sind und/oder andere Nachteile aufweisen. Substituted imidazole derivatives of the formula (II) are of great technical importance for the pharmaceutical and agrochemical industries and are, for example, important intermediates, inter alia in the preparation of compounds which are active, for example, as pesticides. Corresponding imidazoles for use as pesticides and processes for their preparation are described, for example, in WO 2013/180193, WO 2016/039444, WO 2018/130437 and WO 2018/130443. The manufacturing processes described in the prior art, however, include methods that cannot be realized economically from an industrial point of view and / or have other disadvantages.
Insbesondere stellt die regioselektive Einführung des Substituenten Y an Verbindungen der Formel (I) eine große Herausforderung dar. Besonders schwierig gestaltet sich dies durch die beiden chemisch sehr ähnlichen Ringsysteme die in den Verbindungen der Formel (I) aneinander gekoppelt sind und durch die Präsenz anderer sauren Protonen in den Verbindungen der Formel (I). In der Fiteratur ist die Metallierung und folgende Halogenierung von solchen Strukturen auf dem Imidazol Ring bisher nicht beschrieben. In particular, the regioselective introduction of the substituent Y onto compounds of the formula (I) represents a great challenge. This is particularly difficult due to the two chemically very similar ring systems which are coupled to one another in the compounds of the formula (I) and due to the presence of other acidic compounds Protons in the compounds of formula (I). The metalation and subsequent halogenation of such structures on the imidazole ring has not yet been described in the literature.
Nachteilig sind insbesondere bei den üblicherweise verwendeten Fithium- und Magnesiumbasen die geringen chemischen Ausbeuten, die Durchführung bei sehr niedrigen Temperaturen sowie die schwierige Regio- und Chemo-Selektivität der Deprotoniereung aufgrund der hohen Reaktivität von diesen Reagenzien. Manchmal ist eine Transmetallierung mit Zinksalzen wie zum Beispiel Zinkchlorid notwendig, um weitere selektive Reaktionen wie Negishi-Kreuzkupplungen durchzuführen, wie in Organic Leiters 2008, 10, 2497-2500 beschrieben. Die Herstellung ist daher sehr teuer (viele Salze entstehen) und nicht für großtechnische kommerzielle Verfahren geeignet. The low chemical yields, the implementation at very low temperatures and the difficult regio- and chemo-selectivity of deprotonation due to the high reactivity of these reagents are particularly disadvantageous in the case of the commonly used fithium and magnesium bases. Sometimes a transmetallation with zinc salts such as zinc chloride is necessary in order to carry out further selective reactions such as Negishi cross-couplings, as described in Organic Leiters 2008, 10, 2497-2500. The production is therefore very expensive (many salts are formed) and is not suitable for large-scale commercial processes.
Im Hinblick auf die vorstehend geschilderten Nachteile besteht dringend Bedarf für ein vereinfachtes, technisch und ökonomisch durchführbares Verfahren zur Herstellung von substituierten Imidazolderivaten, insbesondere der Formel (II). Die mit diesem angestrebten Verfahren erhältlichen substituierten Imidazolderivate sollen dabei vorzugsweise mit guter Ausbeute, hoher Reinheit und in ökonomischer Weise erhalten werden. In view of the disadvantages described above, there is an urgent need for a simplified, technically and economically feasible process for the preparation of substituted imidazole derivatives, in particular of the formula (II). The substituted imidazole derivatives obtainable by this desired process should preferably be obtained in good yield, high purity and in an economical manner.
Verfahren zur Herstellung von substituierten Imidazopyridinen und deren Vorstufen unter Verwendung von Zink-metallorganischen Basen sind beschrieben in WO 2018/007224, WO 2018/033448, WO 2018/050515 und WO 2018/141955. Processes for the preparation of substituted imidazopyridines and their precursors using zinc-organometallic bases are described in WO 2018/007224, WO 2018/033448, WO 2018/050515 and WO 2018/141955.
Überraschenderweise wurde gefunden, dass in einem Verfahren unter Verwendung einer Zink metallorganischen Base auch substituierten Imidazolderivate der Formel (II) vorteilhaft, insbesondere auch mit hoher Regio- und Chemoselektivität und guter Ausbeute hergestellt werden können. Surprisingly, it was found that substituted imidazole derivatives of the formula (II) can also be prepared advantageously in a process using a zinc organometallic base, in particular also with high regio- and chemoselectivity and good yield.

Vorteilhafterweise lassen sich die substituierten Imidazolderivate der Formel (II) mit dem erfindungsgemäßen Verfahren mit guten Ausbeuten und in hoher Reinheit herstellen. Aufgrund der sehr guten funktionellen Gruppen-Toleranz von Zink-Reagenzien sind Zinkbasen sehr attraktiv. Regio- und chemoselektive Metallierungen von Imidazolderivaten in Gegenwart von stöchiometrischen Mengen
von selektiven Basen werden möglich, auch bei erhöhten Temperaturen, ohne dass eine Arin- Eliminierung stattfindet oder empfindliche funktionelle Gruppen angegriffen werden. Die als Zwischenstufe entstandene Zinkverbindung kann anschließend mit verschiedenen Elektrophilen abgefangen werden wie beispielsweise in Organic Leiters 2009, 11, 1837-1840 beschrieben. Diese neu substituierten Imidazolderivate können dann als wertvolle Synthone weiter umgesetzt werden. Durch das erfindungegemäße Verfahren werden zudem weitere und/oder flexiblere Derivatisierungen von Edukt und Produkt möglich, ohne Synthesenrouten ständig ändern bzw. anzupassen zu müssen.

The zinc compound formed as an intermediate can then be trapped with various electrophiles as described, for example, in Organic Leiters 2009, 11, 1837-1840. These newly substituted imidazole derivatives can then be further implemented as valuable synthons. The method according to the invention also enables further and / or more flexible derivatizations of starting material and product without having to constantly change or adapt synthesis routes.
